To all whom it may concern: 7

3e it known that I, GEORGE J'. S. CoLLrNs, citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification,

My invention relates to improvements in roller bearings rind refers more specifically to improvements in the arrangement of the roller elements with respect to a removable cage in which the balls are. collectively end erence t0 the accompanying drawings, in-

.L' .unicl Figure 1 is a side View of inyinvention showing the adjustable cone. Fig. 2 is n vertical section on indirect line X -X of Fig. 1. Fig. 3 is a side view of the construction of a bearing in which the bearing ungles are somewhat changed from those shown in Fig. 1. Fig. 4; is :1 Vertical section through the center of Fig. Fig. 5 is a top view of a raging having the form shown in Fig. 2. i

lteicrringto the crrcwings A designates an outer ring turned to a suitable angle upon which the main supporting roller eleincnts or bulls revolve.

ll is an annular cone in Fig. 1, turned to a suitable nngl'c to'coniplete the-annular race upon which the main supporting roller elenu-nls or bulls revolve and is threaded to fit within the ring A.

Lcitcr C designates the collar through whirh the axle is installed.

The main supporting roller elements or.

bulls which revolveon the bearing surfaces of the ring A and cone B are marked D.

The cage comprises the main annular bod) E. having portions formed up betweenv the bulls near their peripheries so as to ongugc the annular plate F on the opposite side of the main supporting roller elements or bulls, the connection being made by turlr ing down bendable tips 0 of the body E, into recesses f in the edge of plate 1*, as

shown in 5. The portions of body E formed up between the halls also fir; the space between the body and plate i if desired. however the connecting arms of the body parts riveted together by distance studs in a manner well known in thenrt. The letters c g1, mark the points on the axes of rotation of the main supporting roller elements or balls where they Contact with the cnging.

The cylindricalv rollers or separators (l placed bet-ween the balls to separate them and keep them from contacting thereby eliminate the friction between the balls. These separators are turned 05 to a smaller diameter at their ends and are journnled through the cnging as indicated in the drawings.

The operation of the hearing may he thus describec Assume that the inner ring C is attached to an axle which is stationary and that the rings A and B revolve in a clockwise direction from left to right, the main supporting rollers will also travel in the some direction, while one side of the ball is descending, the other side is ascending, therefore, if the nuiin. supporting rollers or bulls were contacting, their opposing faces would he talringopposite directions. In order to eliminate the friction caused by this opposing motion, the smell rolling sepzi- -rators marked It} are placed between the bulls, and as they are not in contact with either bearing surface, they are free to rotate in the direction given them by their contact with the halls, and they thus rotate in the opposite direction to the halls and travel contrn-clocltw' e. or from right to left. In Fig. 2 the axes of rotation of the balls are horizontal and they contact on each side with the cage at points 5, d. 911 these axes there is no movement of the halls, thus the ceging is by means of this contact with the balls without any-friction which might be caused by the balls contacting with the at any other points than at the: axes of rotation. In F 4 the axes of rotation of the halls are on a line passing. th ough their centers parallel to the inner surface or race ofthc outer ring A, thus the points of contnctin this construction which ire on the axes 0'. rotation, are at points (Z, J. It will thus be seen that by any combination of the angles of races, the caging cnn he so constructed kept from lateral movement 60 E may be omitted and the two he ina points on their axes of thin the outer ring A L maternally shaped to afiord the nails D. The front of the e cage slopes inwardly from .i periphery toward the axis L and the rear side F of the cage llcl with the iront. The frontand in the cage are joined by the connecting acing portions 6''. The screw marked adcd into the outer collar A and enholes or grooves b in the collar B. inc adjustment may be made by the screw a into the slots in the WQtll parts A and B and engaging This is a style of adjustment w rich the bearing can be very d adjnsted.

.ilaiin. as my invention 1. a roller bearing, a cage having d parallel sides, balls located between 7 sides oilthe cage the diameter of the balls being equal to the internal width of was whereby the balls touch the sides e at diametrically opposite points, cage having openings through balls may project in a direction the eenteix the said openings being in than the balls, the space be in supporting roller ele- I tween said sides toward the center being continuously open, and spac'in rollers en; gaging the sides of the cage dietween the balls and retaining the balls, the balls pro jecting between the rollers and toward the center beyond the edges of said sides of the ca e.

In a roller bearing, a revoluble twopart cage comprising as one part a flat an nular side, and as the other part a body having a fiat annular side corresponding to and arranged parallel with the flat side first mentioned, the said body having spacing and connecting portions adapted to suitably separate the annular sides, balls arranged between the saidsides, the space between the said sides being approximately equal to the diameter of the balls, and rcvoluble spacing devices located between the balls, the said spacing portions of the body and said revoluble spacing devices being adapted to retain the balls in. the cage, substantially as described.

In testimony whereof I afiix my. signature in presence of two witnesses.
